Theory in North American Information Systems Research: A Culturomic Analysis

Since its inception, North American information systems (IS) research has relied on a broad and varied collection of theories. The core of this theoretical landscape is an important determinant of the IS research community’s identity, and, as such, researchers have discussed it extensively in recent years.

Unbalanced Agricultural Development in North-east India

Population genetics and origin of the native North American agricultural weed waterhemp (Amaranthus tuberculatus; Amaranthaceae).

UNLABELLED • PREMISE OF THE STUDY The evolution of invasiveness has been extensively studied in natural ecosystems; however, far less is known about the evolution of agricultural invasiveness, despite the major economic impact of weeds on crop productivity. Examining the population structure of recently arisen weeds can provide insights into evolutionary avenues to invasion of agroecosystems....

North American ornithology in transition.

Although they differ in part by history, region, scientific approach and taxonomic focus, many of the memberships overlap and the societies are increasingly holding joint meetings. The largest of these is the North American Ornithological Conference (NAOC). Since 1994, NAOCs have convened rough...
